The study presented in this paper focuses on the subjective opinions of occupants of multistory residential buildings by examining the relationship between occupants’ satisfaction and indoor environment quality, and analysing the effect the problems experienced with noise level may have on general satisfaction and the perceived acoustic quality. The analysis is based on data collected through surveys addressed to adults living in green and conventional buildings. The results show that occupants are very satisfied with their apartments, and subjectively rated acoustic quality received very high scores. The responses indicate that noise from neighbours has been experienced relatively seldom by occupants; however, the analysis shows that it is the factor that has the strongest effect on satisfaction with acoustic quality. We have found that the environmental profile of a building has a significant effect on general satisfaction expressed by occupants; however, this effect has not been confirmed for acoustic quality.

The Relationship

The research focused on the analysis of the interaction of the individual components of the system operationally efficient building – indoor environment quality – user has been conducted since 2014 in the Czech Republic by a team of College of Banking (BIVŠ) employees. The purpose of the research is the evaluation of advantages and disadvantages of operationally efficient buildings by their owners, users or facility managers. One of the most monitored research parameters is the rating of indoor environment quality and its influence in physical and psychological fitness and work performance of the building users. Next, there are also other relationships which are examined – as the importance of the indoor environment quality with regards to other building's parameters, its influence of the estate market value and the users' willingness to participate on the creation and keeping of indoor environment quality. The interpretation of gathered data proved a significant difference of the individual users' demands in relation to their individual preferences. This fact is necessary to respect while design and managing the operationally efficient buildings.

Definition Of

Visual quality is an important component of indoor environment quality and greatly affects inhabitants’ perception of the living space. Nevertheless, the lighting design of residential buildings is usually underestimated by both designers and standards. This paper presents an integrated index for evaluating the visual quality of an indoor environment in residential buildings. The main parameters considered are daylight access, probability of glare from daylight and electric illumination, maintained illuminance, and color temperature. These aspects are evaluated throughout a whole year using a fixed set of metrics and are combined using relative weights. It was decided to also consider qualitative parameters in order to give more importance to some psychological aspects of visual comfort. Finally, the building visual quality index is obtained by a weighted average of the results of each room with the addition of the qualitative parameters. The applicability of the index was tested through the simulation of a dwelling that will be built and monitored in the context of the Comfort for Sustainable Buildings in the Alps (CASA) research project. The building visual quality index proved to be useful during the design process, allowing for improvements in both electric illumination and daylight access through a comparison of different solutions. This study could represent a step towards the holistic evaluation of indoor environment quality.

Indoor Environment Quality

The Special Issue on “Human Factors in Green Building” addresses the design of indoor environment quality for users’ needs. The collected papers cover various building types and the research highlights the different needs of users. In working environments, employees’ stress is the main concern in the workplace design, especially for open plan offices where lack of privacy and over exposure to environmental stress have been reported. In residential environments, residents have great opportunities to adjust their environments to suit their needs; therefore, passive design such as natural ventilation is explored in residential buildings with climates such as cold or humid tropical. In healthcare environments, the papers in this issue are concerned with the needs of patients, especially the older adults who require special care. In learning environments, thermal and visual aspects are investigated for optimal comfort conditions and learning outcomes. The special issue demonstrates insightful critical thinking of indoor environment quality and proposes a new understanding for more practical design solutions. This editorial note is a brief review of the 12 papers, concluding with reflections about design of built environments to meet users’ needs.

The paper analyses the indoor environment in two modern intelligent buildings located in Poland. Measurements of air and globe temperatures, relative humidity and carbon dioxide concentration in 117 rooms carried out in the space of 1.5 years were presented. Thermal comfort of the occupants has been investigated using a questionnaire survey. Based on 1369 questionnaires, thermal sensation, acceptability and preference votes were analysed in view of their interdependency as well as their dependency on operative temperature, which proved to be very strong. It has been found that the respondents did not completely rate thermal comfort and indoor environment quality as very high, although the overwhelming sensations were positive. Apart from the operation of heating, ventilation and air conditioning (HVAC) systems, this might have also been the cause of individual human factors, such as body mass index, as tested in the study, or the finding that people were generally in favour of a warmer environment. Moreover, thermal environment proved to be the most important element for ensuring the well-being of the occupants.

The Difference

Purpose – The aims of this paper is to investigate the overall satisfaction of occupants of green and conventional residential buildings and their perception of indoor environment quality (IEQ) and to study factors that may cause occupants’ dissatisfaction. Design/methodology/approach – Data were collected through a survey sent to occupants of comparable green and conventional multi-family buildings. The difference in responses between occupants of green and conventional buildings was analysed using Mann–Whitney (rank sum) test. The ordered logistic models were applied to the data to test whether the overall satisfaction changes depending on the level of acceptance of indoor environment quality and whether the building environmental profile and the apartment tenure affect occupant satisfaction. Findings – The results show that both categories of occupants are very satisfied with their apartments and that there is no statistically significant difference between the stated overall satisfaction of occupants living in green and conventional buildings, although a difference was found in the acceptance level for thermal and sound quality. The research highlights the importance of occupant feedback, user-friendly technical installations and the ability to control indoor environment. This knowledge is important for designers, engineers and developers alike in enabling them to improve dwelling quality and minimize post-occupancy problems. Research limitations/implications – It was not possible to include physical measurements of IEQ parameters; the analysis is based only on occupants’ responses, which may carry a certain subjectivity. Originality/value – The paper contributes to the understanding of IEQ from occupant perspective and to knowledge on green building performance.
